Violin: The violin hums a note when struck by the hammer tool. You can place between one and twenty violins and move them freely around the simulation window.

In the violin's Properties Box, you can change the note hummed by the violin. You have twelve notes to choose from: C (default), C#, D, D#, E, F, F#, G, G#, A, A#, and B.

The violin is one of nine sound sources in Sound Lab.
